to theadjacent wall of the room or building and itsother terminalsecured to the door.

For this purpose, one terminal of the member 15 is longitudinally.twisted through an arc of 180 to produce the apertured'termi nal ear. orwing 19 which lies in a plane extending at right angles/to" the plane ofthe" body of the member 15; -Screwsor any other suitable fastening meanswhich may be founddesirable may be employed in securing this member 19to the door.- The other terminal of the member 15 is apertured toreceive the bolt 20 which is freely receivedinthe headQOof a wood screwbolt A. The

member A is, offcourse, threaded into the door-casing as showninFig's'.1'and'2. It

will be observed that the spring may swing about the member A as thecentral axis when the door is moved from'open to closed posi-.

tion, or vice-versa.v At the approximate central point of the member 15,there is f formed a notch,'the terminals 21 of which form shouldersservingto hold an attaching clip 22 against longitudinal movement; Thisattaching clip 22 is also formedfrom astrip of sheet'metal which isdoubled'at. its central point and is engaged about the member 15.- Thefolded portion of the member 22 is seated within the notch, 21 as willbe readily observed upon reference to Fig. "3;

Rivets or similar ffastening 'devices'23 are passedthrough. the two armsof: the mem-' ber 22'and are positioned immediately adjacent'the edgeof'the member 15. It will thus be seen'that the screws 23 in connectionwith the terminal shoulders produced by the formation of the notchreferred to serve to 7 hold the attaching clip against'llongitudinalmovenient'onthe spring15. The outer terminaloftheattaching clip isapertured as,

indicated at 24 to 'receive the rounded upper terminal of the rod 16.-A' pair of nuts 25 n are threaded on the terminal of this rod and areengaged against the upper and lower facesofthe cliplso as to hold therod against vertical movement 'thereover. The lower terminal of the rodmember -16-'is bent to form-a hook'26 which is adapted tobere- 4'movably engaged in an ordinary'screw eyelet or similar element 27,carried by thebody portion 17of the weather strip.

The actual construction of the severalparts of my invention having beenthus dis -closed, it now remains to explaln briefly the manner in whichthe various elements operate whenthe device is in use. In'this connection, it will, of course, be apparent that the leaf springs 13'and 14normally tend to" engage flatly against the face of the doorin suchmanner that the flexible sealing strip 18 is'engaged with the thresholdof the door casing forming an air-tight closure which .will prevent theentrance of dust'or the like into the room or building. When the door isopened against the tensionof thespring I 15, the central portion ofgthismer'nberis bowed upwardlyin the manner shownin ing strip 18 from thethresholdor floor.

From the foregoing 'descriptionand after I a perusal-ofthe accompany ngdrawings, it

will be noted that my invention provides a I spring 15 which serves thetwo-fold function of normally holding the'door in closed position" andof lifting the Weatherstrip from engagement with the threshold or fioorp e opening ofthe door.

As shown in the accompanyingdrawings,

it may be advisable to form the lifting rod 16 in two sections whichxarethreaded at their adjacent terminals and are connected by a turn buckle28. This constructionpf-y the lifting rod, of course, enables theuser ofthe device to adapt the rodfor use'in-com nection with different doors.If the con-*- struction of thedoor is "such as to ;necessi tate thesecuring of thespring "15 adjacent its lower terminal, the rod16canbeshort-j ened by means of the turnbuckle so as to accommodate it to theposition of the spring. I If on the other handfthe particularconstructlon of the door makes it necessary to place the spring 15 at a.higher point, the rod 16 can be elongated bytheturn-buckle.

On the other hand,if'my device is'manufac tured in large quantities foruse in connection with doors which are of'similar' lines, i

the rod members 16 c'anibe made as a",one-" plece devlce, thusreducingthe cost ofmanu-c facture.

In reduction to practice, has been found that the form of this inventionillustrated in the draw ngs, and referred'to' in theabove description asthe preferred-embodiment, is

the most efficient and practical; yet-'real-iz ingthattheconditions-concurrent with the V adoptlonof this devlcewillnecessarilyvary, I I

it is desirable to emphasize the fact that va- IlOllS' mlno'r changes indetails of construction, proportion and arrangement f of parts may beresorted to, when required, without 1 I sacr ficlng any of'theadvantages ofthis in vention, as defined in-th'e appended claims. Havingthus described" my invention,

what I claim and desiretosecure byLetters Patent w 1. Thecombination"withfa" door, .of a" weather strip, resilient 'meanssecuring "the T weather strip to the door and; normally holdingthe saidstripin engagement with the floor, and a resilient member freely andadjustably connectedt'othe weather strip'f for lifting the same upon theopening of the door, saidresilientmember serving also to normallymaintain the door in closed position.

2. The combination with a door, of a weather strip, leaf springshingedly connecting the weather strip'to the door and normally servingto hold the same in-engagement with the floor, a leaf spring secured atone terminal .to the door and at the other terminal'to the door casingand normally holding the door in closed position, and means freelyconnecting the second mentioned spring and the weather strip whereby thestrip is lifted and disengaged from the floor upon the opening of thedoor.

3. The combination with a door, 'of a Weather strip, leaf springs freelysecuring the strip to the door and normally serving to hold the strip inengagement with the floor, a leaf spring fixed at one terminal to thedoor and freely connected at its other terminal to the door casing, andmeans connecting the second mentioned spring and the weather strip,whereby the strip is automaticallylifted into spaced relation to thefloor upon the opening of the door.

- 4:. The combination with a door, of a weather strip, and resilientmeans connected to the strip for automatically lifting the same intospaced relation to the floor upon the opening of the door, said meansalso 7 serving to normally hold the door in closed position.

5. The combination with a door, of a weather strip, resilient meansfreely connecting the strip and the door and normally holding the stripvin engagement with the floor, resilient means rigidly connected to thedoor and freely connected to the door casing for normally holding thedoor in closed position, and a rod member'freely connecting said lastmentioned resilient means and the strip, whereby the strip is liftedinto spaced relation to the floor upon the opening of the door.

6. The combination With a door, of a weather strip, means resilientlyconnecting the strip to the door and normally holding the strip inengagement with the floor, a leaf spring connected at one terminal tothe door and at the other terminal to the door casing, said spring beingdisposed to normally maintain the door in closed position, a clip membersecured to the spring, and a rod member freely secured at its upperterminal to the clip and at its lower terminal to the strip, whereby thestripis automati cally lifted into spaced relation to the floor upon theopening of the door.

7. A device of the character described including a leaf spring adaptedto be terminally secured to a door and to a door casing, the said springbeing disposed to normally maintain the door in closed position andbeing provided intermediate its length with a notch, a substantially U-shaped clip member embracing the spring and having its bight portionseated in said notch whereby the clip is held against longitudinalmovement upon the spring, a rod member removably secured at its upperterminal to the clip and being adapted to be freely secured at its lowerterminal to a weather striphingedly mounted upon the door whereby thestrip is automatically lifted into spaced relation to the floor upon theopening of the door.

In testimony whereof I aifix my signature in presence of two witnesses.
